How To Get Rid Of Cat Pee Smell On Mattress: Simple Steps That Actually Help

If you’re searching for “How To Get Rid Of Cat Pee Smell On Mattress,” you’re probably dealing with a fresh accident or a lingering odor that won’t go away. Cat urine can be stubborn, but with the right steps, you can often remove both the stain and the smell without damaging your mattress.

Below are clear, FAQ-style answers to the most common questions people have about cat pee on mattresses.

Why does cat pee smell so strong on a mattress?

Cat urine has a concentrated mix of ammonia and other compounds that can smell strong, especially as it dries. A mattress is thick and absorbent, so the liquid can soak deep into the layers, making the odor more noticeable and harder to remove.

If it isn’t cleaned quickly and thoroughly, odors can linger and even encourage your cat to use the same spot again.

What should I do right away if my cat pees on the mattress?

Acting quickly is one of the most important parts of How To Get Rid Of Cat Pee Smell On Mattress.

  1. Blot, don’t rub
    Use paper towels or a clean cloth to press firmly into the wet area. This pulls out as much urine as possible. Avoid rubbing, which can push the liquid deeper.

  2. Remove bedding immediately
    Strip sheets, mattress protector, and blankets and set them aside to wash separately.

  3. Mark the area
    Once it’s blotted, lightly outline the damp area in your mind (or with a small object next to it) so you treat the right spot later, even as it dries.

What cleaning solution works best for cat pee smell?

For mattresses, gentle but effective ingredients are usually preferred. A common at-home approach uses:

  • Enzymatic cleaner made for pet urine
  • Or a mix of white vinegar and water, followed later by baking soda

Basic step-by-step method

  1. Apply an enzymatic cleaner (if available)

    • Saturate the affected area enough to reach where the urine went.
    • Let it sit as directed on the label so the enzymes can break down the odor-causing compounds.
    • Blot again to remove excess moisture.

  2. If you don’t have an enzymatic cleaner

    • Mix equal parts white vinegar and water.
    • Lightly spray or pour onto the area (not so much that the mattress is soaked all the way through).
    • Let it sit for 10–15 minutes.
    • Blot thoroughly.

  3. Use baking soda

    • After treating with cleaner or vinegar solution and blotting, sprinkle a generous layer of baking soda over the area.
    • Leave it for several hours, or overnight if possible, to absorb odors and moisture.
    • Vacuum the baking soda thoroughly.

Will the smell go away completely?

Many people find that, with prompt and thorough cleaning, the odor becomes faint or disappears. However, several factors affect results:

  • How long the urine sat before cleaning
  • How deeply it soaked into the mattress
  • Whether the smell has been treated more than once

If you still notice a faint smell, you can repeat the process: reapply an enzymatic cleaner, wait, then add more baking soda and vacuum again. Multiple treatments are sometimes needed for older or heavier accidents.

Can I use bleach or harsh chemicals on my mattress?

Using bleach or strong chemical cleaners on a mattress is generally not recommended. They can:

  • Damage the mattress materials
  • Leave strong chemical odors
  • Potentially discolor the fabric

Mild, water-based solutions and cleaners designed for fabrics and pet stains are usually a safer choice. Always test any cleaner on a small, hidden area first.

How can I dry the mattress properly after cleaning?

Drying is a key part of How To Get Rid Of Cat Pee Smell On Mattress, because trapped moisture can keep smells around.

  • Increase airflow: Open windows, use a fan, or place the mattress in a well-ventilated area.
  • Avoid over-wetting: Use enough cleaner to reach the stain, but blot well so the mattress doesn’t stay soaked.
  • Allow plenty of time: The mattress should feel completely dry to the touch before putting sheets back on.

What if the cat pee smell has been there for a long time?

Old, dried urine is often more difficult to remove, but you can still try:

  1. Lightly re-dampen the area with a water and vinegar solution to help loosen dried residue.
  2. Apply an enzymatic cleaner as directed.
  3. Let it sit longer than you would for a fresh stain, if the instructions allow.
  4. Use baking soda afterward and vacuum thoroughly.
  5. Repeat as needed.

If, after several attempts, the smell is still strong or has spread, some people decide to limit use of that side of the mattress or consider replacement, especially if odors are very bothersome.

How can I stop my cat from peeing on the mattress again?

From a mattress-care perspective, focus on protection and prevention:

  • Use a waterproof mattress protector to limit future damage.
  • Keep your bedroom door closed if your cat is known to have accidents.
  • Clean any new spots as soon as they happen so lingering smells don’t attract repeat accidents.

For ongoing or frequent accidents, many people find it helpful to consult a vet or pet behavior resource to understand underlying causes. This goes beyond mattress care but can help protect your sleep surface long term.
